For Back to the Future Day on October 21, the Waco plumber is urging residents to find the date on their water heater before an old tank sends out its own mayday.

Waco, TX (PRUnderground) October 14th, 2026

October 21 is Back to the Future Day, and Mayday Plumbing has a simple challenge for Waco homeowners. Head to the garage, closet, or attic, find the label on your water heater, and look for the manufacture date. If that number looks like it belongs in a time machine, it may be time to start planning for what comes next.

Most tank water heaters last about 8 to 12 years. The mineral-heavy water common across Central Texas can wear them out even faster, because sediment builds up in the bottom of the tank. Warning signs include rumbling or popping sounds, rusty or cloudy hot water, moisture around the base, and hot water that runs out sooner than it used to.

"Most people have no idea how old their water heater is until it fails," said Travis Cole of Mayday Plumbing. "We'd much rather get a call from someone who's curious than from someone standing in an inch of water. Checking that date takes thirty seconds, and it can save a lot of headaches."

The company says fall is one of the best times to take care of an aging water heater, before cooler weather and holiday guests put extra demand on the system. Homeowners who reach out this month can ask the team about ways to make an upgrade easier on the wallet, including options for both standard tank and tankless models.
